This would result in the same error, because x.a is not an lval.
The example that make me ask here was Form1.Caption := Form1.Caption + '.';

AFAIR, there already has been a discussion about += and friends for

In fact I don't see why the compiler not just generates "x.a := x.a + y"
from "x.a += y" before doing any code generating,

from "x.a += y" before doing any code generating, disregarding what x.a
is. Of course an error me
